The DejaVu framework offers access to the Web as
one of the facilities in a collection
of software components for developing
multimedia user interfaces and hypermedia
It provides a vehicle
for experimenting with true hypermedia extensions
to the Web.
Our approach, which is essentially object-oriented,
allows for integrating the Web in applications
and vice versa, for composing a Web browser with support
for sound synthesis, digital video,
3D graphics and virtual reality.
On a software level this is realized by extending
HTML to allow for embedded scripts,
written in a script language that is extensible
with application-defined functionality.
However, in addition to this rather low-level
provision for active documents, our Web browser
component allows for SGML-defined document types
capturing the syntax and semantics of multimedia
This paper gives a brief overview of the various
components constituting the DejaVu framework
and discusses briefly the architectural notions underlying our framework.
We will show
how to employ these components to develop
a Web browser with (client-side) support
for animation, multimedia and virtual reality.
By giving some examples, we will illustrate
our solution to defining the (browsing)
semantics of arbitrary document types by means of script-based
As a conclusion we will discuss the requirements
that must be met for developing
a HyTime compliant browser for the Web.
